The 'Coca Cola' Beach

Post by detectorman5050 » Sun Nov 18, 2018 7:16 pm

I have found a spot at the beach, where the coins come out the black sand looking like they have been immersed in coca cola for decades (bright and shiny.)

Most pre decimals I dig up whether on land, or beach are 'wasted,' so this is a refreshing change.

Have you found a similar effect on your local beach?

Apart from the 1918 penny they look like coins from my youth. The older coin would have been black or very dark green. Nice finds tho'. Much better that the worn and degraded ones I find.

It was 'black sand' on a beach as opposed to estuary mud. I was on a 'red sand' beach 2 weeks ago; lots of pre decimals, but so wasted that I threw most of them in the bin. Looks like the 'red sand' at that beach was acting like a fine sandpaper on the coins.

Below is a 1958 Half Crown, I found on the red sand beach, and it was one of the coins in 'better condition' that I kept.

My coins often come out like that from the black sand (or the Thames) too but they don't stay shiny very long. ::g

Yes, I've noticed that weird process also. You get them out the black sand, and they look brand new. By the time you get home, they seem to have 'gone off.'

I have to say that the ones in my photo, are still looking good a few days later.

I don't know what anaerobic means but of course will look it up. I think that a good analogy for the condition of these finds, is that they seem to have gone through the 'coin equivalent of mummification.'

Oxygen free:

The anaerobic properties of Thames mud means that its treasures are cocooned in an oxygen-free environment, which preserves them .
